6 Claims.

This invention relates to a binding device and material therefor', and more particularly to a binding strap which may be used to bind bundles of objects together or to bind cartons, containers and the like.

An object of the invention is to provide a device for binding loose bundles of objects of materials, such, for example, as shell casings and the like, into a compact body and for supporting containers or cartons. Another object is to provide a device made primarily of non-critical -material which is suitable as a Substitute for steel strapping and .the like. Yet another object is to provide a binding strap which is made essentially of paper. A further object is to provide a device which is easy to handle and which is free of any sharp or cutting edges.

Another object of the invention is to provide a binding strap which is resistant to water and which possesses a minimum of elasticity. Yet another object is to provide a binding strap which is flexible so as to tightly engage the materials to be bound and which at the same time pcssesses sufficient rigidity. to permit the strap to be secured in place with a conventional clamp. A further object is to Provide a binding strap of paper tape or the like, including means for reinforcing the tape and for stitfening the tape to provide the desired rigidity therein.

Other features and advantages of the invention will appear from the following specification and drawing, in which- Fig. 1 isa perspective view of a carton supported bythe binding device of the invention; Fig. 2 -is a .fragmentary detail elevational view showing a clamp applied to the binding strap; Fig. 3 is a longitudinal sectional view taken along the line 3-3 of Fig. 2; Fig. 4-is a transversel sectional view taken along the line 4-4 of Fig. 2; Fig. 5 is a front elevational view partly broken away, showing the construction of the binding strap; and Fig. 6 is a longitudinal `sectional view taken along the line S-I of Fig. 5.

plates a binding strap made essentially of paper which istough, strong and flexible, and which at the Sametime possesses sumcient rigidity to permit the secure attachment thereto of a conventional binding clamp. In addition, the strap may be substantially water-resistant and may possess a minimum of elasticity.

In the embodiment of the invention described herein, a strap l0 may be placed about a container Il with the end portions l2 and Il of the strap in overlapping relation. A suitable clamp Il may be applied to the overlapping ends ,of the strap to secure the strap in position. The longitudinal folds in the tape as illustrated Ordinary paper tape is not suitable as a substitute for steel strapping inbinding cartons, containers and the like, not only because the tape is notF sumciently strong but also because the paper tape is normally so exible that the conventional clamp cannot be securely attached to it. On' the other hand, if the paper is sumciently rigid to permit attachment of the clamp, then it is not fiexible'or tough enough to withstand the strains to which it is subjected. In f a binding strap, great strength and toughness are necessary. lThe present invention contemmay extend throughout substantially the entire length thereof.

` As seen particularly in Figs. 5 and 6, the binding strap may be formed of a ylayer of paper tape l5 wrapped or Wound about a strip I6 of stiifening material, such as cardboard, paperboard, chipboard, wood veneer, or the like. Preferably, the tape is folded longitudinally about the edges of theV paperboard strip I6 and the lateral edge portions I'l and I8 of the tape may then be folded over each other in overlapping relation to enclose the paperboard strip I6.

Any suitable type of tape may be used for this purpose. Preferably, as shown, the tape includes a pair of sheets of paper' IS and 20, with an adhesive material 2| carrying reinforcing fibers 22 interposed between the two layers of paper. 'I'he adhesive material may be asphalt or other suitable material and may thus serve the function of increasing the moisture resistance of the tape as Well as securing the reinforcing fibers 22 in position. Preferably, the reinforcing fibers are longitudinally disposed with respect to the tape, as shown in Fig. 5.

The paper sheets I9 and 20 may be of any suitable type and are preferably a high wet strength kraft paper which will prevent scuing of the paper when wet.

The reinforcing fibers 22 may be of sisal or of any suitable fllamentary material, such as thread or cord or the like.

The strip IB should be of a material, such as ,i paperboard or veneer wood, which possesses some.

rigidity and acts as a stiil'ener for the tape which `is foli'ledthereabout. The width of the layer of tape should be more than twice the width of the strip It so that when the tape is folded longitudinally about the strip II, the edge portions I1 and Il overlap to secure the strip within the tape. If desired, any suitable, means may be used for securing the overlapping edge portions Il and Il -in overlapping relation. For example,v

the overlapping portion may be glued to the portionI therebeneath with a water-soluble adhesive or with a water-resistant adhesive, such4 as asphalt or a resin adhesive. Ifdeslred, as illustrated in Fig. 5, stitches 23 may be passed through the unit to secure the tape and the strip Il in proper position.

The clamp I4, which is used to secure the overlapping ends of the tape to each other to fasten the same about a carton or container, may be of conventional construction. Thus. the clamp may include portions. 24 and 2B which are turned back upon the body 2i of the clamp. Preferably, the clamp Il is made of metal.

The clamp Il is applied by placing the end portions I2 and Il of the strap Il within the clamp and then exerting pressure on the portionsl for an interlocking structure in which registering projections and recesses secure the end portions I2 and Il of the strap I0 against longitudinal movement. i

If desired, a coating of a water-resistant material, such as asphalt or a resinous material, may be placed on the outer surface of .the strap to prevent the formation of mold. When such a material as asphalt is used, it will, in addition, tend to hold the strap in place on the materials which it binds and prevent slipping of the strap.

If desired, the insert` or strip I8 of stiffening material may be treated with a suitable material, such as asphalt or a resinous material, to render the insert water-resistant. VIn this manner, the entire strap may be made substantially waterthe insert is not only rendered water-resistant but, in addition, the tacky asphalt surface tendsv to prevent slippage-of the insert within the folds of the tape. The treating material is preferably appliedin the liquid state so that the stiifening strip or insert will be substantially impregnated with the material.

readily disposed of after it has served its purpose.'

The binding strap is thick and compressible so that when the clamp is applied thereto, the strap is compressedvand distorted by the clamp to form the interlocking structure which holds thel strap in position. l I

Although the invention has'been described in connection with a particular embodiment,v it will be apparent that modifications and changes may Ind scope of the invention.
